AI Image Generation in 2026: Complete Guide to Seedream, Nano Banana, and Frontier Models
Text-to-image, style-locked variants, catalog production — the 2026 image generation workflow inside Flik AI.
AI image generation in 2026 is split between three frontier models, each tuned for a different kind of output. Seedream 4.5 leads on cinematic composition and stylized art. Nano Banana Pro leads on photo-realistic images and precise editing. Nano Banana 2 is the fast tier. Here's how to use each — and when to pick which.

- Images with readable text (signage, labels, UI) → Nano Banana Pro
- Reference images for text-to-video → any tier, pick by fidelity need
Prompting for image generation
Image prompts share structure with video prompts — subject, context, style, camera, lighting — but skip action. Example:
For model-specific prompting tips, see /seedream-prompts and /nano-banana-prompts.
Production workflows
- Catalog shots: generate 5–10 variants with Nano Banana 2 (fast tier), pick the winner, regenerate the keeper with Nano Banana Pro for final quality
- Brand consistency: save a reference set (logo, palette, previous hero images) as a project template and reuse across every new image generation
- Image-to-video: generate a style-frame with Seedream 4.5 or Nano Banana Pro, then pipe it as a reference into Kling 3.0 Pro / Veo 3.1 / Seedance 2.0 for motion
- Aspect ratio control: all three models support 21:9, 16:9, 4:3, 1:1, 4:5, 9:16 — pick before generation based on your destination
